My loudmouth 1 is pretty loud at times I wish it was not as loud so I could talk on my phone. I'm about to do H/C/I headers when I do this I'm going away from the Loudmouth and adding cutouts with a nice magnaflow or something around that style.

LM1 is gonna be the loudest for the simple fact that the muffler is just a straight pipe

As far as my exhaust, i have Flowmaster 80 series, 3'' exhaust cutout, Mac Midlength headers, removed the cat and mine sounds pretty brutal. im sure theyre are lounder things out there, but im pleased with the way my set up sounds. Deep low rumble that deff turns heads.

ive got hooker super comp lt's to a 4 inch y pipe to a single 4'' dynomax race bullet. its ******* loud.. its barely quieter then a cutout. main difference is that its not raspy like a cutout. it sounds killer at WOT. but god damn did i say its loud? i get cops tailing me all the time, sounds like im drag racing when im barely accelerating.

Have you seen the inside of the dynomax bullets? I believe the specs say that they are 3dB quieter over straight.. That's not much difference is you ask me.
